With medium to large power plant and desalination plants, the power plant's cooling water flow is likely to be several times larger than that of the desalination plant, reducing the salinity of the combination. Another method to dilute the brine is to mix it via a diffuser in a mixing zone.
In China a desalination plant was planned for Tianjin in 2010, to produce 100,000 m³ of desalinated seawater a day. [9] [10] In Spain in 2004, 20 reverse osmosis plants were planned to be built along the Costas, expecting to meet slightly over 1% of Spain's total water needs. [11] [12] [13]
Schematic of a multiple effect desalination plant. The first stage is at the top. Pink areas are vapor, lighter blue areas are liquid feed water. Stronger turquoise is condensate. It is not shown how feed water enters other stages than the first. F - feed water in. S - heating steam in. C - heating steam out. W - Fresh water (condensate) out.
Single phase desalination is predominantly accomplished with photovoltaics that produce electricity to drive RO pumps. Over 15,000 desalination plants operate around the world. Nearly 70% use RO, yielding 44% of desalination. [38] Alternative methods that use solar thermal collection to provide mechanical energy to drive RO are in development.
A microbial desalination cell (MDC) is a biological electrochemical system that implements the use of electro-active bacteria to power desalination of water in situ, resourcing the natural anode and cathode gradient of the electro-active bacteria and thus creating an internal supercapacitor.
The first method utilizes an ejector system motivated by steam at manometric pressure from an external source in order to recycle vapor from the desalination process. The form is designated ejectocompression or thermocompression. Using the second method, water vapor is compressed by means of a mechanical device, electrically driven in most cases.
An independent water and power plant (IWPP) or an integrated water and power project is a combined facility which serves as both a desalination plant and a power plant. IWPPs are more common in the Middle East , where demand for both electricity and salt water desalinisation are high.
